I thought I had already posted this, but I guess not cause I can't find it.

What is the box fill requirement for a 120/240V Dryer receptacle? This is on a 30-a circuit with 10-3, and using 14-30 receptacle and Dryer cord.

What I'm needing is a plastic remodel box, if they're available. I didn't see any Carlons on a Home Depot online search.

I'm thinking the one pic'd below is too small.

do you like this one better?




that's just a 2 gang old work (remodel) box. CARLON HOME PRODUCTS # BH234R

just check to be sure the recep will mount on a 2 gang box (no screw bosses in the middle, There are two sets, each offset from the center so as to accommodate 2 switches, receps, whatever). I believe they are designed for the screw offset of a 2 gang box.
well heck. The image doesn't want to post.

go here http://electrical.hardwarestore.com/14-45-electrical-boxes-plastic.aspx?viewAll=yes&sortBy=

and scroll down to just about the very bottom

never mind. Now it posted.

hmm, don't know if that will work or not, Nap, because of the screw mounting. Is there a mud ring or some such to fill the obvious gap in the box?

"Screw boss"? never heard of such a contraption, but I've used those words in phrases several times :laughing:

Com'on, Nap, what do you use for these flush mounted receptacles? :)

the screw "boss" is simply the little nub with the hole in it for the screws to screw into. As to fitting into that box; that is why I said make sure the recep you get will fit a 2 gang box. I did a quick look on the 'net and it would appear it is common for a dryer recep to have mounting holes for a 2 gang box.

I have used the old work box for dryer receptale as well just be extra carefull when you mount the box make sure you get them good and tight it will fit in nice.

Otherwise I go old school is use the deepwell 4X4 box { actaully 4X4X2 1/8 inch } and screw it to the stud that useally do the trick otherwise may have to make a cross brace to support the box.

Merci,
Marc

yeah, Marc, I'd like the 4x4, but I don't see any "old-work" 4s. I'll figer something out

thanks

A two-gang box is standard issue for a dryer receptacle, as is a two-gang sized plate.
You do NOT need a 4x4 box with mud rings and all. Besides, good luck trying to find one.

Use the box shown in post #2. Better yet, get a two-gang "Smart Box" and attach it to a stud.
